Hentenna measures
 
Hentenna has 3 important measures. They are H: height, W: width and S: (See right picture for the reference).

 Following list is these standard measures for each armature bands.
 For the adjustment, please refer to top page of Hentenna but the only thing you have to do is adjusting "S" measure moving a,b points.
